Only had my car a month or so now, and the alarm has gone off by itself about 7 times now, even when it is sitting in a locked garage. I thought it must have been the motion sensors, but since it does not have any, it cant be. I don't really want to say anything to the dealer at the moment, as with it being an intermittent fault, they will probably have to take the car off me for weeks to diagnose it.
